MEANS FOR SAVING RADIATOR-OVERFLOW.

Specification of Letters Patent.

Passed Oct. 7, 1919.

Application filed December 16, 1918. Serial No. 266,96Ul.

To all whom it may concern:

Be it known that I, LESLIE E. OPIE, a citizen of the United .States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Means for Saving Radiator-Overflow; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the radiators of automobile engines, the object of the invention being to conserve the water supply in such radiators by providing means adapted to catch and save the overflow therefrom.

The nature of the invention is fully disclosed in the description and claims following, reference being had to the accompanyin drawing, in which %igure 1 is a front elevation of a device embodying my invention as in use. Fig. 2 is a central section of the catch-vessel shown in Fig. 1. Fig. 3 is an elevation of the same as seen from the side. Fig. 4 is a plan view of the same.

In the drawing, the numeral 1 designates an automobile engine radiator of a familiar t pe. This is provided with the usual overow pipe 2, which is herein shown terminating in an elbow outlet 3, so as to avoid any kink in the section of hose 4 connecting with it.

At some convenient point, as for example a shelf 5 attached to the main frame 6 of the automobile body, is mounted a vessel 7 to catch the overflow from the radiator. This is here shown as a can, divided vertically by a partition 8, and the separate compartments closed by ti ht-fitting lids 9 and 10. The former is a cose lid, adapted to seal the compartment 11 raotically airtight. In this compartment 1s placed a tube 12 extending to the center of the bottom, and at its upper end formed with an elbow 13 to receive one end of the section of hose above mentioned. The other compartment has a similar tube 14:, whose upper end opens into the com artment 11. A venthcle 15 is made in a lid of this compartment 16. For convenience in attaching the vessel to its so port it is provided with depending ears 1 and by means of wires 18, or the like, the vessel is secured to its supporting shelf. In the vented chamber is placed a small quantity of some non-volatile liquid 19, preferably heavy oil. largely arrests any outflow of steam, and practically seals the chamber against the escape of Water.

The operation of the device will be evident from the foregoing. An excess of heat and pressure in the radiator will cause the steam and water therein to overflow. 1f the radiator cap 20 is tight, as it should be, the overflow can only escape into the receiver 7. The closed chamber therein serves to catch the hot water of condensation, any residual steam passing through the tube 14 to the bottom of the chamber 16. Here the steam is further arrested, and further condensation takes lace, no water, and very little steam escaping, even under the severest conditions of service. When the heat and pressure subsides in the radiator, assuming it to be properly tight, the contents of the receiver will be nearly all sucked back into the radiator. This serves to keep the radiator properly filled, without attention on the part of the operator, except to add a little water from time to time to compensate for a little waste which cannot be avoided.

The device is useful everywhere, and especially in semi-arid regions, to conserve water at all times. It serves also to cut off much of the cost of up-keep in freezing weather, by arresting the waste of antifreezing material, of which alcohol is usually re arded as the most practical ingredient.

aving thus described my invention, I claim:

1. A device for arresting waste and evaporation from automobile radiators, com rising a vessel provided with a tube exten ing from the top to the bottom thereof and a vent near the top, means for connecting the upper end of said tube with the overflow pipe of the radiator, and an arresting medium, such as oil, adapted to float on the water overflowin into said vessel, substantially as describe 2. A waste-arresting device for radiators, comprising a vessel separated into two cham- This very bers by a vertical partition, one of such chambers being closed and the other vented, a tube 1n the closed chamber openg g out connection of said first mnued tube with the overflow pipe of the radiator.
